Is this who i think this is
Studying for finals is like encountering the silence: the second you look away from the book you forgot what you just read
I have got a lot of growing up to do
In case you’re in need of motivation, have some from the Doctor.
You can do it!
so tonight my philosophy professor had these nasty bruises all over her arms and she stopped mid-lecture to say “sorry you guys have to look at my bruised-up body, my friend brought a stripper pole over for thanksgiving and that shit is not easy. tip your strippers. tip your strippers well” and then immediately kept talking about philosophy
RHIC by the Numbers
Our atom smasher — the Relativistic Heavy Ion Collider (RHIC) — is a pretty stunning feat of engineering.
- These tubes run around the 2.4 mile circumference of the collider, which is big enough to be seen from space.
- They are made up of 1740 superconducting magnets, strung end-to-end.
- To make RHIC’s magnets carry electricity without resistance, they are cooled by liquid helium to -452 degrees Fahrenheit, nearly absolute zero.
- In all, RHIC contains 25 tons of helium, enough to fill all the balloons in the Macy’s Thanksgiving Day Parade for the next 400 years!
- The magnetic field within the tubes acts on the beams of charged particles to steer them around the circle and into collision with one another thousands of times per second.
- The particle beams are made up of 111 separate bunches, each containing billions of ions.
- Those ions travel at 99.5% the speed of light, making 80,000 trips around the ring every second.
- The temperature inside a collision reaches four trillion degrees Celsius — that’s 250,000 times hotter than the center of the sun!
- RHIC collisions pack so much energy into a such a small space, it’d be like stuffing all the energy used in the U.S. in one year into a cube with sides measuring just one quarter of the width of a human hair.
All of this comes together so that this experiment can cast an eye on the conditions of the universe as it existed 13.7 billion years ago. Wowza!
